I'm sorry, but according to the rules of opinions, I can and will say that Final Fantasy VII is the worst RPG in history. I played the game, I beat the game, I hated the game. It really is that simple.
But I'll go a step further. I don't know about you or anyone else here, but I have not played every single RPG there is to play. I haven't even played half of them. So those don't count in. Out of the RPGs that I have played, Final Fantasy VII counts as the worst among them. I didn't like it, so it is exactly that simple.
